can't parse std::vector<std::byte>

[Spongman]

this worked in v2.1.1, but no longer works in v3.9.1:

int main() {
	std::vector<std::byte> rg;
	nlohmann::json::parse({rg.begin(), rg.end()});
}

include/nlohmann/nlohmann/json.hpp:5164:40: error: no matching function for call to ‘nlohmann::detail::iterator_input_adapter<const char*>::iterator_input_adapter(nlohmann::detail::iterator_input_adapter_factory<__gnu_cxx::__normal_iterator<std::byte*, std::vector<std::byte> >, void>::adapter_type)’
 5164 |         : ia(input_adapter(first, last)) {}

i tried just passing the iterators directly:

int main() {
	std::vector<std::byte> rg;
	nlohmann::json::parse(rg.begin(), rg.end());
}

but this gives a bunch of these:

include/nlohmann/nlohmann/json.hpp:7423:59: error: cannot convert ‘char’ to ‘std::byte’ in initialization
 7423 |                 std::array<char_type, 4> true_literal = {{'t', 'r', 'u', 'e'}};
      |                                                           ^~~
      |                                                           |
      |                                                           char

This works on the latest develop branch (I did not check 3.9.1):

#include <iostream>
#include "json.hpp"

using json = nlohmann::json;

int main()
{
    std::vector<std::byte> rg = {(std::byte)'t', (std::byte)'r', (std::byte)'u', (std::byte)'e'};
    auto j = nlohmann::json::parse(rg.begin(), rg.end());
    std::cout << j << std::endl;
}

Output:

true

are you going to tag a release containing this fix any time soon? or should i just try to cherry-pick this into 3.9.1?

[nlohmann]

It is fixed with #2550 and will be part of the next release. I do not have a release date, though.

[nlohmann]

Duplicate of #2546.

i see that 3.9.1 was nearly 11 months ago. would it be possible to have separate branches for bug fixes and new features and prioritize releasing fixes to bugs like this?
